Human Dental Pulp Vasculogenesis Evaluated by CD34 Antigen Expression and Morphological Arrangement

Journal of Dental Research, 2003
Vasculogenesis describes the process by which endothelial precursor cells form new blood vessels. To characterize the topography and the cellular processes underlying vascularization of human dental pulp, we examiend the expression of the human hematopoietic progenitor cell antigen CD34.

Structural and functional features of the CD34 antigen: an update.

Journal of biological regulators and homeostatic agents, 2001
CD34 is a heavily glycosylated type I transmembrane molecule, that can be phoshorylated by a variety of kinases including Protein kinase C and Tyrosine kinases. The classification of epitopes detected by different CD34 MAbs has aided the selection of appropriate antibodies for use in specific clinical and research laboratory settings.

Expression of haematopoietic progenitor cell-associated antigen BI-3C5/CD34 in leukaemia

Leukemia Research, 1989
The expression of progenitor cell-associated antigen CD34, defined with monoclonal antibody BI-3C5, was investigated in cells from 109 patients with leukaemia. No reactivity was found in chronic leukaemias, whereas 31% of acute myelogenous leukaemia (AML) and most non-T, non-B acute lymphoblastic leukaemia (ALL) expressed CD34.

CD34 antigen expression in children with philadelphia chromosome-positive acute lymphoblastic leukemia

Cancer, 1991
One characteristic of Philadelphia chromosome (Ph')-positive acute leukemia is the occasional presence of both lymphoid and myeloid features in the same leukemia. This phenomenon supports the theory that this subtype of acute leukemia arises from lymphoid-myeloid stem cell, pluripotent progenitors.

[Sorting CD34 antigens: objectives, biological and clinical results].

Presse medicale (Paris, France : 1983), 1999
CD34 SORTING: CD34 sorting is a means of selecting hematopoietic stem cells among heterogeneous populations of cells. The technique is based on the fact that only hematopoietic stem cells (excepting a few tumoral cells) carry the CD34 antigen. Generally this type of manipulation is performed in case of stem cell grafts or for the treatment of certain ...

Silencing CD34 antigen in human hematopoietic stem cells

2008
CD34 is a highly glycosylated transmembrane protein strongly expressed on hematopoietic stem/progenitor cells (HSPCs); despite its importance as a marker of HSPCs, its function is still poorly understood, even if a role in cell adhesion has been demonstrated.

[CD34+ antigen expression relating to prognosis in acute myeloid leukemia].

Zhongguo shi yan xue ye xue za zhi, 2008
To explore CD34(+) antigen expression in new diagnosed acute myeloid leukemia (AML) and analyze the prognosis for CD34(+) AML patients, the expression of antigen CD34 in 238 AML patients was detected by indirect immunofluorescence assay. The results showed that CD34 in 92 out of the 238 patients (38.7%) were positive, there was relationship between the
